Description
Technical field
The utility model relates to pipeline stopping transportation pressure venting techniques fields, and in particular to a kind of pipeline is opened small-diameter hole and opened
Hole machine.
Background technique
Oil and gas transportation pipeline in use, will receive the influence of various factors, can install instrument on existing pipeline
Instruments and meters picks out new branch pipeline, and press and open holes can complete this work in the state of safety and on-line production, and
The existing tapping machine for opening small-diameter hole is all manual operation, time-consuming and laborious, and cutter rotation and feed speed unshapeliness influence knife
The service life of tool, there are security risks.
Utility model content
The utility model provides a kind of pipeline and opens small-diameter hole tapping machine, to solve manual operation of the existing technology
The rotation of time-consuming and laborious and cutter and the interrupted problem of feed speed.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of pipeline opens small-diameter hole tapping machine, including drive motor, motor fixing sleeve, shaft coupling, main shaft, feed shaft,
Feed change case, input shaft, positioning bolt, sealing axis, boring cutter and aperture connector, motor fixing sleeve by positioning bolt with
Sealing axis outer diameter on keyway link together make motor fixing sleeve can only comply with keyway direction move up and down, drive motor and
Main shaft is connected by shaft coupling, driving spindle rotation, and boring cutter is connected below main shaft, and feed change case connects feed shaft, feeding
Axis is connected with sealing axis, and the screw thread in feed shaft leads to head and seals the external screw thread mating connection on axis top, and main shaft is fixed on feeding
On axis, feed shaft rotation is driven to realize that feed shaft moves up and down by rotation feed box input shaft.
Sealing gland is arranged in above-mentioned sealing axis bottom.
When the utility model operation, after the completion of tapping machine is installed on aperture valve simultaneously pressure testing, feed change case is rotated
On input shaft, boring cutter is moved on aperture pipeline, drive motor is started, drives boring cutter rotation, then by revolving manually
The feed motion for driving boring cutter to the input shaft on gearbox is rotated into, after aperture, stops drive motor, reversely rotates
Input shaft on feed change case proposes boring cutter into aperture connector, completes aperture.
The utility model realizes that boring cutter rotary motion revolving speed is constant, and avoiding can be manually rotated by installing drive motor
When the sometimes fast and sometimes slow and time-consuming and laborious problem of cutter revolving speed；Installation feeding gearbox makes feed shaft by deceleration hand feed
Feed speed is uniform, when avoiding big when feed shaft feed speed when being directly fed manually the problem of small and easy swaging clamp, thus
The cutter of protection keeps cutting-tool's used life longer, with easy to use, design is reasonable, structure is simple and safe and efficient excellent
Point.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model feed change case；
Fig. 3 is the schematic diagram of the utility model sealing axis；
Fig. 4 is the schematic diagram of Section A-A in Fig. 3.
1 drive motor, 2 motor fixing sleeves, 3 shaft couplings, 4 main shafts, 5 feed shafts, 6 feed change casees, 7 input shafts, 8 in figure
Positioning bolt, 9 sealing axis, 10 sealing glands, 11 boring cutters, 12 aperture connectors.
Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4: a kind of pipeline opens small-diameter hole tapping machine, including drive motor 1, motor are solid
Surely set 2, shaft coupling 3, main shaft 4, feed shaft 5, feed change case 6, input shaft 7, positioning bolt 8, sealing axis 9,11 and of boring cutter
Aperture connector 12, drive motor 1 can be hydraulic motor, air motor or motor form, and motor fixing sleeve 2 passes through positioning spiral shell
Bolt 8 links together with the keyway on sealing 9 outer diameter of axis, so that the direction for making motor fixing sleeve 2 that can only comply with keyway is transported up and down
Dynamic, drive motor 1 and main shaft 4 connect driving spindle 4 by shaft coupling 3 and rotate, and boring cutter 11 are connected below main shaft 4, realization is opened
The rotary motion of hole knife 11, feed change case 6 connect feed shaft 5, and feed shaft 5 is connected with sealing axis 9, the setting of sealing 9 bottom of axis
Sealing gland 10, the screw thread in feed shaft 5, which leads to head and seals the external screw thread on axis top, to be cooperatively connected, and main shaft 4 is fixed on feed shaft 5
On, it drives feed shaft 5 to rotate by rotation feed box input shaft 7, to realize that feed shaft moves up and down, and then realizes on main shaft
The bottom and top feed of cutter moves, and realizes aperture operation.
When the utility model operation, after the completion of tapping machine is installed on aperture valve simultaneously pressure testing, feed change case is rotated
On input shaft, boring cutter is moved on aperture pipeline, drive motor is started, drives boring cutter rotation, then by revolving manually
The feed motion for driving boring cutter to the input shaft on gearbox is rotated into, after aperture, stops drive motor, reversely rotates
Input shaft on feed change case proposes boring cutter 11 into aperture connector 12, completes aperture.
